UNITED STATES PATENT OFFICE,

JOSEPH BARKER, OF SUMMERFIELD, ALABAMA,

MACHINE FOR HULLING AND CLEANING PEAS.

SPECIFICATION forming part of Letters Patent No. 273,010, dated February 27, 1883.

Application filed November 27': 1882. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH B. BARKER, a citizen of the United States, residing at Summerfield, in the county of Dallas and State of Alabama, have invented certain new and useful Improvements in Machines for Hulling and Cleaning Peas, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention relates to improvements in machinery for hulling peas, and has for its object the rapid and efficient hulling and cleaning and separating peas from the hull. This is attained by the mechanism illustrated in the drawings, forming a part of this specification, in which Figure 1 is a side elevation, with some of the parts broken away to show its internal construction. Fig. 2 is a plan view. Fig. 3 is a detail view of the vertical disk \V, showing the general arrangement of the ragged spikes to; Fig. 4, a detail view of the disks W and W, with the ragged spikes 'w to interlaced with each other, and a part of frame A in section. Fig. 5 is a detailed view of the Fig. 6 is a detailed view of the steel plate S, showing the ragged surface 'w Fig. 7 is a detailed view, enlarged, of three of the ragged spikes w and a part of the disk W, casing H, and steel plate S. Fig.8 is a section of the casing H H steel plates S S, hopper H, and part of the frame A. Fig. 9 is a detailed sectional view of the removable casing H.

H is a hopper, into which the peas are fed.

H is a removable casing, secured by screws or otherwise to the frame A, which covers the upper portion of the disks W W.

H is the lower casing, and has an opening, H for the discharge of the peas and broken hulls.

A is the frame, which holds and supports the various parts of the machine.

W is a wheel or disk, firmly attached to a shaft, L, with which it revolves.

W is a wheel or disk, firmly attached to the frame or body of the machine A.

w are spikes, of metal, having their outer surfaces roughened. They are attached to the faces of the disks W W, and stand at a right angle thereto. When the disk W is revolved its spikes interlace with those of the opposite disk, W, and the peas are drawn between these opposing spikes, the ragged surfaces of which break and tear the bulls to pieces.

R is an incline in the lower part of the frame, and carries the peas and broken hulls in the direction of the blast-fan F, the blast from which drives the chaff and broken hulls out from the machine in the direction of the arrows, Fig. 8, through the opening R and permits the peas to drop through the open space 0 of the fan-casing into any suitablereceptacle provided for the purpose.

H is a removable casing (preferably of sheet metal) which covers the disks W W.

S is a steel plate, curved to the shape of the casing H, and secured by bolts and rivets to the inner surface thereof, or in any other convenient manner.

The concave surface of each of the steel plates S S is made ragged by numerous irregularlyplaced sharp points. The lower plat-e, S, is attached to the casing H in any convenient manner. The casing H is made preferably of sheet metal.

In revolving the disk W its outer circle of spikes 10 come in close proximity to the steel plates S S, and the ragged surfaces of the spikes and of the steel plates act upon the peas and hulls which pass between them, and break and tear the hulls in such manner that when subjected to the action of the fan-blower the hulls are blown off in one direction, whilethe peas, now perfectly clean, fall in another.

P is a pulley secured to the shaft L. A driving-belt passes over this pulley and then over the pulley 1?, attached to the fan-shaft, to which it imparts motion when the shaft L is revolved. The shaft L is provided with suitable bearings, and has a pulley, P, from which it receives its motion.

Having described my invention, what I desire to secure Letters Patent for, and to claim,

is- I 1. In a pea-hulling machine, the vertical revolving disk XV and stationary disk W, each ICC In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH R. BARKER.
